It is prohibited to learn Torah in the bathroom (source needed).
How far does this prohibition go? Are we not allowed to say pesukim, but allowed to think them? Is there a difference between tanach and Torah sheba’al Peh?
Can one sing (pesukim based songs) in the bathroom (seeing as he doesn’t mean to learn, just to entertain himself)?
Can someone figure out/ check zmanim and other stuff that will help him perform mitzvos (but aren’t learning/ mitzvos themselves)?
What do our sources say about this?
